This plant is recognized by its yellow, four-parted flowers arranged in a small umbel-like cluster. It blooms from May to August. It likes disturbed areas, moderate soil moisture, and dabbled shade. Celandine poppy is often found growing in association with other well-known pest species such as garlic mustard, Dame’s Rocket, and yellow rocket.
A member of the Poppy or Papaveraceae family, Greater Celandine is difficult to pull because the leaves often break off at soil level when tugged on, leaving behind a long tap root (like a dandelion) which oozes a yellowish sap. Best to use a trowel or shovel on this one.
